fix(auth): preserve login cancellation and error codes

[AmanVarshney01]

What changed

Interactive deployment now runs prisma auth login --json with TTY stdin and captures its structured result. Explicit denial and prompt cancellation are treated as cancellation. Real auth failures retain the Prisma CLI error code for troubleshooting and telemetry. No login output is parsed with regex or inferred from a generic exit code.

Reproduction

With an isolated auth file, the published Prisma CLI reports AUTH.LOGIN_DENIED for OAuth denial. Ctrl-C at its paste prompt currently reports CLI.INTERNAL_ERROR; prisma/prisma-cli#275 fixes that to CLI.PROMPT_CANCELLED (verified against a locally built CLI). Previously create-prisma discarded both codes by inheriting all child streams, so both became prisma_auth_command_failed.

Verification

Unit tests, typecheck, formatting checks, build, and Windows creation smoke pass. The published create-prisma@pr117 preview also scaffolded a fresh minimal/Postgres/npm project with quiet JSON output, and the generated app built successfully. npm run dev:composer provisioned the local database and app, and GET / returned HTTP 200 with seeded users. Full local e2e ran 11/12 tests; the Turborepo dev:composer case hit a pre-existing named local database with stale migration state, unrelated to this auth change. Depends on the CLI fix only for Ctrl-C classification; this PR independently preserves structured login failures.

Summary by CodeRabbit

• Bug Fixes
  • Prisma sign-in now supports interactive terminal input and output, allowing users to respond to authentication prompts directly.
  • Sign-in denials, cancelled prompts, and interrupted login processes are treated as authentication cancellations. Other errors, such as network failures, continue to be reported as failures.
• Tests
  • Updated authentication tests to verify interactive terminal behavior and handling of Prisma sign-in errors.

Walkthrough

Interactive authentication now runs Prisma login through runPrismaJsonCommandEffect with inherited stdin and stderr, piped stdout, and no --no-interactive flag. Specified Prisma login and prompt errors, plus interrupted or cancelled child-process errors, map to authentication cancellation. Tests check the command options and the outcomes for structured CLI error codes.

Priority: ➖ Normal

Merge Risk: ⚪ Minimal · up to d58ed

Login preserves cancellation and diagnostic error codes, with tests covering interrupted login without JSON output. Mergeable subject to normal checks.
